Newlywed Meghan Markle accompanied husband Prince Harry’s grandmother, The Queen, on her first solo royal engagement to Cheshire on June 14.

The Duchess of Sussex – who acquired the new title after marrying her 33-year-old spouse in May – made sure she followed the very strict royal beauty rules for the occasion, as she wore the 92-year-old monarch and Kate Middleton’s favourte pink/nude nail varnish.

The former Suits actress stunned in a fitted nude, midi dress, which had a cape detailing to cover her shoulders, which she paired with black accessories.

And Meghan made sure her nails matched her ensemble.

Many will be unaware of the royal nail rule Meghan, and her royal relatives, have to stick to.

Kate Middleton and Queen Elizabeth rarely wear nail polish – according to some sources it’s simply royal etiquette, as fake nails or coloured nail polish is deemed vulgar by the royal family – but they do occasionally make exceptions.

But the one nail polish Prince William’s grandmother does approve of is Essie’s Ballet Slippers.

Essie revealed the Queen’s hairdresser sent them a letter requesting Ballet Slippers, because it was “the only colour Her Majesty would wear.”

The shade is a classic pink polish with a subtle, sheer finish and has won a lot of awards, so it’s no wonder it’s the Queen’s favourite.

The royal’s much-loved nail polish costs just £7.99 from Boots.

Meghan has not only worn the nail varnish on her first royal engagement with Prince Philip’s wife, but also on her wedding day.

While the Duchess of Cambridge adhered to the Queen’s tradition and wore the exact brand in the same shade for her wedding to Prince William in 2011.
